IMPROVEMENT IN SPINNING-JACKS.

TO ALL 'WHOMAIT MAY CONOERN: Be it known that I, FRANCIS R. PEARsoN, of Germantown, vcity and Acounty of Philadelphia, and State of Pennsylvania, have invented certain vnew and useful Improvements in Spinning-Jacks for spinning woollen yarn; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to thc annexed drawings, vmaking a part of this specification, in'

Figure 1 is a top view.

Similar letters in` the drawings refer to like parts.

'My improvement consists in a mechanical arrangement of a friction motion to a spinning-jack, to assist the operator or spinner in thc working of the same. v

To enable others to make and Yoperate my improvement, I will proceed to describe its construction and operation, reference being had to the annexed drawings, making a part of this specification.

I1, in figs. 2 and 3, is the mztin drivingjbolt, which communicates motion to the jack by the pulley 3. The belt shifter fis constructed and supported in the usual manner, with this exception, that the shifter-bar is not positively connected to the levers which operate it by the move-mentsl ofthe carriage and twist-gearing;v that is to say, that this lever, on all jacks heretofore built, connecting the twist gear with the shifter-bar, is slotted at that 'part where it'connects with the shifter-bar. In this slot is a pin or stud, fastened to the shifter-bar. This slot I dispense with, and by the action of the spring 5 thepin is drawn against the lever connecting with the twist-gearing. The twist-gearing and the ever connecting it with the shifter-bar are notv shown in the drawings, as theseparts are all old and well known to spinners and operators'of spinning-jacks. The object is to allow the friction motion to operate without moving the twist-gearing. To this shifter I fasten the spiral spring 5. The pin z', fig. 3, presses against the right-angled lever u, whe-n the belt is en the loose pulley. The lever u is fastened to the frame by the stand fw, iig. 3. In one of the arms of this lever is a slot. (See details.) The end of this rests on the nut on the connection-rod lu. The rodv is connected to the T-shaped lever y, which is pivoted one studlin the stand Z, which stand is fastened to the floor. To the lower end of the leverg is connected the rod r. This rod is supported by the stands 1, 2, and h, fastened to the floor and between the centre slip and the race-belt of the jack. Theirod 7 extends out to the end of the slip. On vthe outer end of the rodr is cut a thread, on which is fitted the lug 0 and nut t. At the extreme bottom of the lever g is fastA ened the spiral spring 6. This spring is made of greater power than the spring 5, connected to the shifter-bar f, fig. 1. The other end of the spring is fastened to the floor. In the top of the stand i is the catch e, fitted to a. stud pin so that it will workfreely. C represents the carriage, n the faller. To this feller is connected the wire p, having a loop at the lower end. This wirel is steadied by the staple x at the bottom ofthe carriage, iig. 2. On the back of the carriage is a stand.- In this stand is fitted a stud, s, set at the same .height as the top of tne lever g.

The operation islas* follows: In putting the carriage up, the stud s, in the rear of theca-rriag'e, presses the lever g, and forces back the rod r. When, by this back movement, the catch e locks en the lug o, 'and the car-' rage is drawn out the full str etch, the operator *backs oi; and in putting down the faller 1t the loop on the wirep raises the catch e, the spring 6 draws the lever g'back till the nut t on the end of the rod r strikes the stand z, which is set so as to allow the spring to shift the belt on the tight pulley 3 sufficiently fa-r to assist the operator Vin putting up the carriage, it being regulated by the nut t. As -soon as the carriage is put up, and before thel jack is put in gear, the friction is taken olf, so that, when the operator stops to piece up ends that may be broken, the frictienlmill be entirely olf.-

Having thus described my invention, I would state that I am aware there are other devices invented and patented, which accomplish the sarneobj'ect, difering only in their construction and operation. The advantages in my improvement are, first, my arrangement, which does not positively connect the belt-shifter bar to the twist-gear, and controlling the movements of the saidbarlrin one Y'direction by connecting it to a spiral spring. The same result may be effected by an elliptic spring, but a. y'spiral' spring is preferable. Second, by cutting the regulating screw on the rod r, and operating the catch from the front of the carriage, which arrangement enables me to construct a. very simple yet eicient and adjustable friction motion, which I claim .to be n decided improvement on all other friction motions in use as known'to me.

Claims I claiml 1. Actua/ting the belt-shifterburf in one direction by means of the twist-gearing, and in the other direction by the spiral spring` the whole combined and arranged substantially as described amd for the purpose set forth. k

2. I claim the combination and {t1-rangement of the catch c, loop j), and fuller 91,. constructed :Ls described, und operated from the front of the carriage, substantially :is described :md for the purpose set forth 3. I claim the combination of the rod r, lug o, catch e. stztnd h, :md nut t, when constructed as described for the purpose sct forth.
